[Qemu-devel] [PATCH v4 01/31] include/exec/helper-head.h: support f16 in helper calls

["Alex Bennée" <alex.bennee@linaro.org>]

This allows us to explicitly pass float16 to helpers rather than
assuming uint32_t and dealing with the result. Of course they will be
passed in i32 sized registers by default.
